When my wife complains about little squeaks and rattles in her vehicle, I say "let me fix that for you", then I reach over and crank up the volume on the stereo, then ask her if she can still hear it, BOY if looks could kill I would have died very young!!!!
In my defense, if it's indeed something serious I fix it ASAP, but I still can't resist messing with her, she falls for it everytime after all these years!!
